Biological soil conditioner

Abstract

The invention discloses a biological soil conditioner. The biological soil conditioner is prepared from, by weight, 5-10 parts of plant ash, 40-60 parts of biological straw, 20-40 parts of organic materials, 5-25 parts of humic acid, 3-6 parts of biological active enzymes, 2-10 parts of biological strains, 5-15 parts of ammonia fertilizer, 1-5 parts of trace elements and 3-15 parts of animal faeces. According to the biological soil conditioner, the biological straw and the organic materials are adopted as composting materials, the strains are added for preparing fermented compost, the biological soil conditioner can effectively improve soil properties, improve soil organic matter, increase the crop yield and improve the crop quality, the cost is low, and the preparation technology is simple.

Description

technical field [0001] The invention relates to the technical field of agricultural bioengineering, in particular to a biological soil improver. Background technique [0002] With the development of agricultural technology, chemical fertilizers have been widely used, but it has caused many problems. Not only the large amount of base fertilizer and chemical fertilizer is used, but also a large amount of top dressing is used, which seriously damages the soil aggregate structure, reduces the air permeability, and reduces the activity of aerobic microorganisms, which will destroy the soil structure and lead to a decrease in soil fertility. It will even pollute the environment. The various organic matter, beneficial bacteria and active enzymes in many farmland soils are gradually destroyed and thus lose their natural benignity. The pH of the soil also tends to develop in different degrees due to the abuse of various chemical products. There are some bad phenomena in the soil. C...

Problems solved by technology

Not only the large amount of base fertilizer and chemical fertilizer is used, but also a large amount of top dressing is used, which seriously damages the soil aggregate structure, reduces the air permeability, and reduces the activity of aerobic microorganisms, which will destroy the soil structure and lead to a decrease in soil fertility. It will even pollute the environment. The various organic matter, beneficial bacteria and active enzymes in many farmland soils are gradually destroyed and thus lose their natural benignity. The pH of the soil also tends to develop in different degrees due to the abuse of various chemical products. Some bad phenomena in the soil

Compared with chemical fertilizers, microbial fertilizers have obvious advantages in improving fertilizer use efficiency, increasing crop yields and protecting the ecological environment. For example, CN104402648A discloses a kind of improved soil biological fertilizer, which provides nitrogen, phosphorus, and potassium fertilizers for crops in an all-round way. Crops provide the necessary trace elements. Applying this fertilizer will not compact the soil, can improve the soil structure, and has strong water retention capacity. However, the formula of the fertilizer is relatively complicated, and a large amount of metal salts are added, which may easily lead to environmental pollution.

CN104387166A discloses a kind of bio-fertilizer for improving soil, the raw material is cheap and easy to get, environment-friendly, but the improvement effect is general
